Vapor pressure data for an organic compound are: T °C psat kPa -50. 9.46 +10. 148.42 a. Estimate the vapor pressure in kPa at -20° C? You can't be too precise here, but you can beat the accuracy of 9.46+148.42 kPa = 78.94 kPa. b. What is the heat of vaporization in J/mol at -20° C? You may assume the vapor phase is an ideal gas and that the vapor molar volume is much greater than the liquid molar volume.
